The substance is ethylene glycol.

What is density?

The term density is the ratio of mass to volume. We have two substances here which are ethanol and ethylene glycol. We have the mass of the solution as shown in the image in question 7 in the attachment to the question.

Mass of the solution = 381 - 250 = 131 g

Volume of the solution = 4 fl oz

1mL= 0.0338 fl

x = 4 fl oz

x =4 fl oz*  1mL/0.0338 fl oz

x = 118.34 mL

Density = mass/volume =  131 g/118.34 mL = 1.11 g/mL

The substance is ethylene glycol.
